Rev Limit

[sjc59]

Hi guys if i was to up the rev limit on a 16v abf engine currently as good as standard how high will the abf lump go before it goes bang? What would a sensible limit be or should i not change it from standard?

you should not change it.... unless you bolt the flywheel on properly.

I think the bottom end is safe for 7500rpm, thats what I have read somewhere before..... I can only see a point of upping your limiter if you have done some engine work, cams, p&p head, etc.... mine rev's to 7400rpm.

I know F2 Stu is 8500rpm or around that and Rob T's 9000+rpm I think but they both got a lot of work done.

Yeah i thought as much i do have work planned just not yet i'll play it safe for now and tweak it when the time comes.

Yeh i mean if you put a bumper like the one on your sig on the beeza, the air flow will mean its safe to rev to like 9k...

hehe.

m0rk, havent you got a dyno graph of a standard abf? Something about the power not dropping off after 7k

The term; "OWNED" comes to mind. Was that yours?

 

[F2 Stu]

[F2 Stu]

Can we rename this thread to "Shizzle F2Stu has broken"

Most of those pics don't look very wallet friendly.
